Title: Improvements in or relating to thermostatic control mechanism
IPC: H01H37/52
Filed: 1946-02-06
Abstract: 607,633. Current-supplying stands for heating appliances. EUREKA WILLIAMS CORPORATION. Feb. 6, 1946, No. 3719. Convention date, Feb. 7, 1945. [Class 39(iii)] [Also in Groups XIII and XXXVII] A stand for a cordless electric iron embodies a switch 16 actuated by a semicircular bimetallic element 12 having its lower edge resting on a collar 26 supported by spring fingers 24 of an annular disc 22 located by a boss 18 on the base 10. The upper edge of the bimetallic element resiliently engages the surface of the iron when positioned on a rest plate 36. The latter has a cap 38 which passes through a spacer 34, a slide 14, and an insulating block 20, and is engaged by a screw 40. thereby holding these components together. The insulating block 20 has a pocket 44 containing a plate 46 and a ball 48 which supports the slide 14 which is free to move through a slot provided between the spacer and the insulating block. The spacer 34 has two pockets 52 containing balls 54 which roll between the top of the bifurcated arms of the slide 14 and the bottom of the rest plate 36. The bifurcated arms straddle the cap 38 and a plate 66 which is clamped between the spacer and the insulating block and is located by a boss 68 of the spacer. A pin 70 attached to the end 72 of the bimetallic element loosely engages a hole in the plate 66; the other end 76 of the element engages a pin 74 attached to the slide. An apertured guard 28 is detachably secured to the base 10 by tabs 32 and has a lip 90 located in the bimetallic element. As the bimetallic element increases in diameter due to heating of the iron, the slide moves to the right eventually opening the switch. As the element cools, a spring arm 80 closes the switch, which action may be assisted by a spring finger 88 formed integral with the disc 22, and bearing against an end of the slide.

Manufacture.-A nickel grid produced by electroforming is placed in a frame and lowered on to convex die and heated in vacuo at 650‹ C. for fifteen minutes, and after cooling is cut to the required size. The grid is placed on a concave glass meniscus (Fig. 3c, not shown) between graphite dies and the assembly heated in argon above the softening temperature of the glass for 30 minutes. After cooling, the dies are removed and traces of graphite are removed by brushing with calcium carbonate, then introducing into acetic acid, and finally rinsing in distilled water.

Title: Improvements in or relating to fuzes for bombs, flares and the like
IPC: F42C15/20
Filed: 1942-04-03
Abstract: 567,035. Bomb fuzes. IMBER, J., HEBARD, H. C., and IMBER RESEARCH, Ltd. April 3, 1942, No. 4464. [Class 9 (i)] Relates to time fuzes for aerial bombs, which may be set to act when the bomb has fallen through a predetermined distance. The fuze comprises a two-part train of fuze composition, one part 22 of which is of fixed length, whereas the other part 26 is of variable effective length and is coiled around a rotatable disc 24, 25, the axis 33 of which is at right angles to the axis of the bomb. The fixed part 22 ends with a powder pellet 28a in the hollow axis of the disc, a radial passage 27 in which leads to one end of the variable train 26, as shown in Fig. 4. A flash aperture 29 is provided in the base 2, in radial communication with the magazine 31. The setting is effected by rotating the disc 24, 25 by an external handle 34 so as to place the passage 27 in the desired angular position relative to the flash aperture 29. When ignited, the lead-coated composition 26 burns until the aperture 29 is reached, whereupon the flash strikes into the magazine 31. At the time this happens, the bomb is falling nose downwards, and the aperture 29 cannot therefore become clogged by molten lead or other fragments. Ignition of the fuze train is effected by a striker 6, which is normally held cocked by a safety pin 7 and balls 8 retained by a tapered cup 12. Axial displacement of the cup to free the balls is regulated by a screw 13 operated by a wind-vane 14 during descent of the bomb. The wind vane is enclosed by a cap 15 which is held in place by spring arms 17 until it is pulled off when the bomb is dropped. The fuze train is vented through a radial passage 37 after a closure 38 has been blown out by the explosion of a pellet 39.
